Abstract
Wastewater is now being considered more as a resource rather than a waste. Technologies are now available to treat wastewater to acceptable standards for reuse. In small communities or industries, small decentralized wastewater treatment systems can be used to treat and reuse water for purposes such as irrigation, industrial reuse, groundwater recharge or even potable water augmentation. In this article, a description of some of the technologies that can be adopted by small communities is given. Decentralized wastewater management is also becoming popular in single homes where the householder is responsible for treatment and discharge of wastewater on the premises. Due to increased awareness even among lay people, technologies are now being used to treat and reuse domestic wastewater on-site for various purposes. In this article some of these technologies such as suspended growth aerated wastewater treatment systems (AWTS) and packed bed filters are described in detail. Irrigation, being the most common reuse option, techniques such as evapotranspiration, land treatment by drip irrigation and advanced FILTER techniques are also discussed.
